Valvoline's MST part number, if you are interested in ordering from places like NAPA: 787301. Since they say HST is formally approved and MST is not, I'm still going to stick with BMW oil because I'm not buying a 55 gallon drum of oil. Only 5w-40 HST as listed here:
http://www.valvoline.com/pdf/synpower.pdf
shows a Total Base Number (TBN) of 10, which like I said before is an indicator for longevity.
BTW- My wife's oil looked pretty thick when it had 120 or so miles until red/due. She last had the oil changed at the dealer, so I'll see next time I do a change how it looks, now that I know for sure I put BMW oil in... |
I tried to look it up on the castrol website when I first got the car and I was extremely confused also, I didn't know why it didn't have a number on the website but the cap says "castrol."
